UnsatisfiedLinkError

on first start (using java 11, osx, spacemacs) I get this:

I experience the same issue using OpenJDK 64-Bit Server VM 12.0.2+10 on MacOS. I believe the issue is related to/similar to https://github.com/AdoptOpenJDK/openjdk-build/issues/1211.

When I changed the JDK version to 11.0.5+10 it worked.

Switch jdk to 12.0.1 should fix it
